Footnotes:

1) Standard frequency stability (±20,±25,±50ppm & others available)

2) V

3) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization.

RMS jitter bandwidth of 12kHz to 20MHz.

4) Tpd is phse shift between the falling edge of pin 4 at 2.0V and the rising edge of pin 5 at 2.01V.

5) Open to enable pin also enables the output.

6) Internal high frequency power source decoupling.
